as thread, comprising interdigitating sets of bar l members having supporting means which during operation of the reel rotate about axes which are inclined to each other and in which reel the axis, of the supporting means for each set of bar members is contained within the periphery of the other set. By providing improved means for adjusting the inclination of the axes of rotation of said supporting means, the present invention makes it possible to adjust the pitch of the helical turns of thread wound on the reel.

For convenience, but in no sense of limitation, the invention will be described in connection with a reelof such type operating on the principle of that shown and described in British Patent- No. 413,414. Said reel comprises two wholly rigid sets of bar members, each set being of substantially circular cross section and rotatable as a whole about an independent axis displaced from that of the other set. Preferably the axes of rotation of said sets of bar members are disposed in inclined relation in parallel planes which are slightly spaced from each other, since with this relation of the axes the most efiicient advance of the thread is obtained.

In such a reel, the reel advances the thread lengthwise thereof in a plurality of spaced, generally helical turns during rotation of the sets of bar members about their axes. The offset relationship of the axes causes each thread turn to be carried by the bar members of both sets and, to be transferred from the bar members of each set to those of the other during the rotation of the reel, certain of the bar members of each set being retracted within the periphery defined by such thread-carrying bar members of the other set. axes causes the thread to advance.

It is desirable, under certain conditions, that I the angle between the axes of rotation of the sets of bar members be adjustable, since in this manper the pitch or spacing of the helical thread turns on the reel, and consequently the length of thread stored on the reel, can be varied. This .The inclined relation of the is particularly desirable in the continuous processing of thread wherein the thread is subjected to one or more processing treatments while being continuously but temporarily stored on the reel, since the time of processing of the thread can be adjusted without changing the speed of rotation of the reel by'suitably changing the length of thread stored on the reel. Moreover, it is also often desirable that the pitch of the helical turns stored on the reel be capable of adjustment when it is desired to employ the reel to Wind material of different widths on the reel.

It is also a desideratum that any variation in the angle of inclination between the axes of rotation of the reel, members be accomplished without varying the amount of offset between such axes; i. e., without moving the axes out of their spaced, parallel planes when they are adjusted relatively to each other,

For instance, if delicate material, such as artificial silk thread, is being subjected to liquid processing treatment while stored on such a reel, and particularly if it is being processed under conditions such that a film of processing liquid is formed which extends for a substantial distance lengthwise of and entirely around the reel, the amount of oflset between the axes of the sets of bar members is critical. It has been found that the offset should not be so large that the retracting bar members of each set can withdraw sufliciently within the periphery. defined by the thread-carrying bar members of the other set to cause the film of processing liquid formed between such retracted bar members and the thread turns to break. The abrupt snapping of the breaking film will' disarrange the turns of thread or' the filaments thereof,

' causing entangling and subsequent breakage of such turn); when they are subsequently unwound from the reel.

The retracted bar members should, however,

be withdrawn ,sufliciently so that they cannot ployed as described immediately above, if the amount of inclination between the axes of rotation of the sets of bar members is adjustable, the adjustment preferably should not result in a change in the amount of oil'set.

Figure2l is a sectional elevation of said reel from line 2i2l of Figure 20. Figure 22 is a sectional elevation through the adjustment means of said reel from line 2222 of Figure 21.

In Figures 20 to 22, inclusive, as also in Figures 1 to 19, inclusive, like reference characters refer to like parts.

The reel illustrated in Figures 1 to 3, inclusive, as embodying the invention is of cantilever form, being supported from one end only and having its other end unsupported. It comprises two rigid reel members i and 2, each of saidreel members being generally circular in cross section and including a set of spaced bar members which extend longitudinally of the reel. The bar members of each reel member are interleaved with those of the other reel member, as shown in Figure 3. Each reel member is mounted for individual rotation about an axis inclined to that of the other reel member.

The bar members 3 of reel member I are formed integrally with a cylindrical body portion 4. The latter includes a hub portion by means of which reel member I is concentrically mounted on shaft 5 for driving relation therewith. Shaft 5 is journalled in frame member 5, rigidly supported from one end only thereof. Because of the manner in which it is mounted on shaft 5, reel member I may be termed the concentric reel member.

Reel member I is held by a cup nut 8 threaded on the end of the drive shaft 5 against a collar 1' .mounted on the shaft. The collar 1, in addition to serving as means against which the concentric 'reel member I can bear, also serves to locate the illustrated embodiment of the invention, it embodies a supporting member I2 by means of which it is rotatably mounted on frame member 6. Supporting member 12 has rigidly mounted thereon a metallic sleeve 13 which serves as the bearing surface. In addition, supporting member l2 serves to carry arigid cage-like member l4 embodying a set of spaced longitudinally extending bar members I5 which are interleaved with thebar members 3 of the concentric reel member I.

Cage-like member I is preferably of one piece cast or molded construction, having formed ,integrally therewith at the end thereof adjacent the unsupported end of the reel an annular ring 16 fixed to the inner portions of bar members l5.-

Formed integrally therewith at the other end of cage-like member I4 is an external annular ring I! fixed to the outer portions of the bar members 15. Said external armular ring I! serves as the means by which said cage member I5 is mounted on the supbortingniember H, as by the bolts I8 in the illustrated'embodiment of the invention.

If the reel is to be employed in the processing of thread, as by means of processing liquid applied to the thread on the reel, it is desirable that it be so constructed that it is not attacked by the processing agents. For this reason, the space between the concentric and eccentric reel members is closed off by a suitable seal 19 which may be formed of. flexible reagent resistant material such as rubber, being clamped to the hub portion of the concentric reel member I as by spring ring 2| and having its other edge clamped in the eccentric member. In the apparatus shown, the outer edge of the seal I9 is provided with a plurality of ridges 22 which are clamped between the supporting member l2 and a suitable washer 23 formed of reagent resistant material, the washer being urged against saidridges 22 by shoulders about axis E, which, as shown in Figures 2 and 3,

is disposed in a plane U offset by an amount from axis C. As shown inFigure 1, axis E is also disposed in inclined relation to axis C. The disposition of the axes C and E in offset and inclined. relationship results in advance of thread lengthwise of the reel in a series of generally helical turns.

As is evident from Figure 2, rotation of the drive shaft will cause concentric reel member i to rotate therewith. Contact of the bar members 3 of said concentric reel member with the bar members l5 of the eccentric reel member will cause said eccentric reel member to rotate about its axis 132.. During such rotation of each reel member about its own axis, as is apparent from Figures 2 and 3, the bar members of each reel member will project beyond the periphery defined by the bar members of the other reel memher over a portion of the circumference of the reel. Consequently, thread turns wound about the reel will be carried partly by the bar members of both reel members, and, as the reel members rotate, the thread in each turn will be transferred from the bar members of one reel member to those of the other and back again.

Furthermore, due to the fact that thread start-. ing on a rotating cylinder always travels at right angles to the axis of rotation of said cylinder, the inclined relation of the reel membersshown in Figure 1 causes the thread carried by the bar members of both reel members to advance lengthwise of the reel in'generally helical turns. The pitch of the helix formed by the turns; i. e the distance that the thread will advance in one revolution of the reel, is determined by theangleof inclination X (Figure 1) between the ax es C and E. For the'direction of rotation indicated by the arrow in Figure 3, the thread will advance lengthwise of the reel toward the unsupported end thereof.

In both of the illustrated embodiments of the invention, the adjusting means comprises a member carried by the frame member on which the first-mentioned eccentric reel member is journalled and. cooperating therewith, a rotatable intermediate member operating between said firstmentioned member and said frame member. By relative rotation of said intermediate member with respect to both the frame member and the member supporting the eccentric member, any desirable relation of the axes, within limits determined by the size and shape of the parts, may be obtained. Indeed, by suitably adjusting both said intermediate member and said first-mentioned member; 1. e., the member supporting said eccentric reel member, the angle of inclination of the axis of the eccentric reel member with respect to that of the concentric reel member can be changed to a variety of different positions in which, however, the axis of the eccentric reel member is still disposed in the plane U.

In the embodiment of the invention illustrated in Figures 1 to 19, inclusive, the adjusting means comprises two nested sleeves and 26, of which the inner sleeve 25 is mounted on frame member 6. Outer sleeve 26 is mounted on inner sleeve 25 and has rotatably mounted on it the supporting member I2 forming part of the eccentric reel member 2. The inner and outer surfaces of each sleeve comprise surfaces of revolution, being preferably cylindrical in shape. The axes of the inner and outer surfaces of each sleeve are inclined to each other.

By suitable rotation of one or both of the sleeves with respect to each other and/or with respect to the frame member 6, a wide variety of relative positions of the axes C and E can be obtained. By suitable rotation of the sleeves with respect to each other and with respect to the frame member 6, it is possible to 'move the axis E in a fixed plane U parallel to the axis C from a position in which there is no relative inclination of the axes C and E to one inwhich there is a maximum inclination, as determined by the shape of the sleeves; indeed, it is possible to reverse the direction of inclination of the axes,

still keeping them in the same plane, so that V for a given direction of rotation of the reel the thread can be caused to travel in the opposite direction lengthwise of the reel. The-preferred shape of the sleeves 25 and 26 is shown in the drawings.

Sleeves 25 and 26 are so formed that when the adjustment means is assembled, the axes of the internal and external surfaces of both sleeves 25 and 2B intersect at a common point P which is fixed for all positions of the sleeves. The point P is preferably disposed adjacent the unsupported end of frame member 6, although it may be located at other positions. The illustrated position is desirable since the crossing point of the axes C and E of the reel members, which is determined by the point P, is at the end of the thread-bearing periphery of reel members I and 2. i

The relation of the parts and of the various axes can be understood from Figures 4 to '7, inelusive, which show the parts adjusted so that the angle X between the axis E and the projection of the axis C on the plane U is at a maximum.

The outer surface of frame member 6 is cylindrical, terminating in a shoulder 21 spaced from the unsupported end and disposed perpendicularly to the axis A of the outer surface of frame member 6. As shown in Figures 4 to I, inclusive, said axis A is parallel to and offset from axis C of the drive shaft; 1. e., from the axis of the concentric member, by an amount 0, which is the offset desired for the reel. .The inner screws 28 in sleeve 25 which extend into a circumferential groove 29 formed in said frame member 5. The groove 29 extends perpendicularly to the axis A of the external surface of said frame member, the end of said sleeve 25 contacting said shoulder being also perpendicular to said axis A. The external surface of sleeve 25 is of generally cylindrical form and is inclined at an angle Yto the internal bore of said sleeve, the axis B of said external surface intersecting the axis A, which is the axis of the internal bore of said sleeve 25, at P, Sleeve 25 is provided with an external shoulder 3| perpendicular to the axis B of the external surface of said sleeve.

The outer sleeve 26 is mounted on saidinner sleeve 25, being provided with an innercylindrical bore which fits snugly but nevertheless rotatably about the external surface of said inner sleeve 25. The external sleeve 26 is located endwise on inner sleeve 25 by bearing against shoulder it on said inner sleeve 25. The contacting end of said outer sleeve, as well as shou1- der M, is' perpendicular to the axis B or the inner surface of sleeve 25. One or more set screws 32 threaded into sleeve 26 extend into a groove 33 extending around the external surface of inner sleeve 25 at right angles to the axis B, which is common to both the outer surface of inner sleeve 25 and the inner surface of outer sleeve 25.

The outer surface of sleeve 26 is of cylindrical form and is adapted to carry the supporting member ill for eccentric reel member 2 for rotation' about its axis E. The outer surface of said external sleeve 26 is so inclined to the inner bore of said sleeve that the axis E of said outer surface, which is the axis of rotation of the eccentric member 2, is inclined at an angle Z to and intersects the axis B of the inner surface of outer sleeve 26 at the point P. The sleeve 26 is provided with an external shoulder 36 perpendicular'to the axis E which serves to aid in locating eccentric reel member 2 endwise. Said reel member is urged against said shoulder by the resilience of the seal IQ.

In the illustrated embodiment of the invention, the angle Y between the axes of the internal and external surfaces of the inner sleeve 25 is equal to the angle Z between the axes of the internal and external surfaces of the external sleeve 26, this being preferable for reasons to be later explained. In the position illustrated in Figures 4 to 7, inclusive, sleeves 25 and 25 are so related with respect to each other and with respect to frame member 6 that the angles Y and Z lie in the common plane U. The latter passes through axis A and is ofiset from axis C by an amount 0, being disposed parallel to said axis (1 at right angles to the direction in which said axis A is offset from axis 0. Consequently, as shown in Figure a, angles Y and Z add to form angle X between the axes E and A, such angle X constituting the total angle of inclination of axis E of the eccentric reel member with respect to axis C of the concentric reel member.

In the position illustrated in Figures 4 to 7, inclusive, this disposition of the axes can be obtained by rotating sleeve 25 through angle W and sleeve26 through the angle V from a common datum point. The latter may be taken as a point on the frame 6 lying in the plane of the axes A and C. The angle X is thus the maxi-' reel is smaller than that occurring when the parts are in the relation shown in Figures 4 to 7, inclusive. In the adjustment shown in Figures 8 to 11, sleeves 25 and 26 are turned with respect to each other and with respect to the frame member 6 so that the axis B of sleeve 25 does not lie in the plane U but at an angle thereto, while sleeve 26 is turned so that its axis E does lie in theplane U. In other words, the sleeves are so turned with respect to each other that their angles do not add to form a maximum angle X, but are so related with respect to the frame member 5 that the resultant angle X lies in the desired plane U. This may be accomplished by turning the inner sleeve 25 through the angle W from the aforesaid datum- 'point and by turning the external sleeve 28 through angle V from said datum point. 4

In the position of the axes illustrated in Figures 12 to 15, inclusive, the sleeves 25 and 26 are so turned with respect to each other that the axes C and E are parallel; consequently, no advance of the thread can take place. In thi relationship, as shown in Figure 15, the sleeves 25 and 26 are so turned with respect to each other that they subtract; i. e., so that the thickest portion of each sleeve is in contact with the thinnest portion of the other sleeve. Thus the inclinations of the twov sleeves in efiect compensate, the axis E of the outer surface of the external sleeve 26 being coincident with the axis A of the internal surface of the internal sleeve 25. No matter in what position the composite sleeve formed of sleeves 25 and 25- when related as shown in Figure 15 is turned with respect to the frame member 6, the axes C and E will, of course, always be parallel because of the equal sizes of the angles Y and Z.

The position illustrated in: Figures 16 to 19, inclusive, shows that sleeves 25 and 26 may be so adjusted that the angle of inclination X with respect to the frame member is in the opposite direction from that previously shown. The position shown in these figures constitutes a typical intermediate position and is similar to that shown in Figures 8 to 11, inclusive, except for the fact that the parts are so turned that the angles X, Y and Z extend in the opposite direction.

That is, from the common datum point the internal sleeve 25 has been turned through the angle W in a direction opposite to the angle W shown in Figures 8 to 11, inclusive, while the external sleeve 26 has been turned to the angle V in a direction opposite to the angle V of said Figures 8to 11.

In each of the positions illustrated, the angles W and V to which the internal and external sleeves, respectively, are turned from a common datum point are equal. This follows from the fact thatthe angles Y and Z between the internal and external surfaces of said sleeves are equal. If the angles Y and Z were of different sizes, it would be necessary that the angles W and V similarly be of different sizes in order to obtain adjustment of the axis E in the desired plane U. Of course, plane U in which it is desired to adjust axis E can itself be disposed in relationships other than that shown, even in one in which the plane passes through the axis of the concentric member, 0. While the reel can operate under such conditions, the best results are obtained when the plane U is disposed parallel to and perpendicular to the direction of offset from the axis C, as shown. 7

In the illustratedembodiment of the invention, the parts can be easily adjusted with respect to each other by reference to pointer 35 rigidly fixed to the frame member 6 in such manner as to extend over sleeves 25 and 26.

Each of said sleeves is preferably marked with the pitch of the thread turns desired, although, of course, each may be marked in fractions of an inch, number of turns per inch, or the like. In the system employed, the markings 36 are so arranged that when similar numbers on both sleeves are turned to .the pointer 35, the reel is adjusted with its axis E in the plane U to give the spacing of thread turns corresponding to the selected number; Plus and minus markings may be provided, the minus markings being so arranged that when two like minus numbers are turned to pointer 35 oppositedirections of inclination result, such, for instance, as that shown in Figures 16 to 19, inclusivel The embodiment of the invention shown in Figures 20 to 22, inclusive, constitutes a modification of that above described.

In this embodiment of the invention, the inclined surfaces are not provided on curved sleeves but on flat surfaces. Member 6a is the frame member having journalled therein drive shaft on which is concentrically mounted concentric reel member I. Member 6a supports member 28a, which carries the eccentric reel member 2. As before, a collar 1 is provided on drive shaft 5 against which collar 1 concentric member I is held by cap nut 8. A second collar .la is provided to bear against frame member 6a in order to aid in locating shaft5 lengthwise.

Intermediate member 25a bears against the face 31 of frame member 6a., which face is disposed perpendicularly to the axis of rotation C of the concentric reel member. Intermediate member 250 has an opposite face 38 which is inclined to the face bearing against face 31 of frame member 6a. Supporting member 260. comprises flange portion 39, bearing against the inclined surface 38 of intermediate member 25a, and a tubular portion 4|, which supports eccentric reel member 2 the axis E of which is inclined to the surface of member 2641 bearing against surface 38 of member 25a.

Intermediate member 25a is rotatably mounted with respect to frame member 6a, being provided with a bore therethrough by means of which it is located on the shoulder 42 of frame member 6a. Similarly, supporting member 26a is adjustably mounted on intermediate member 250., being located by a shoulder 43. These parts are so related that three axes intersect at a common point P; namely, (a) the axis corresponding to axis A about which member 251: is rotatably mounted on frame member to, which axis is perpendicular to surface 31 and offset from axis C by an amount 0; (b) the axis correspond- 26a is rotatably mounted on intermediate member325a, which axis is perpendicular to surface 38 and (c) the axis E of the external surface of tubular portion 4| about which 'the ccentric member 2 is journalled.

Moreover, members 25a and 26a are so formed that on member 25a the angle corresponding to angle Y of the previous embodiment between the axes corresponding to axes A and B is equal to the angle on member 26a, corresponding to angle Z of the previous embodiment, between the axes corresponding to axes B and E.

Consequently, the axis E can be adjusted in a common plane,,which corresponds to the plane U of the previous embodiment, by suitably adjusting the members 25;; and 26a with respect to each other and with respect to frame member 6a. The same method of adjustment outlined above can be performed in the present case; i. e., the angles through which the 'mernbers 25a and 260: are turned with respect to a datum point on frame member 6a. can be equal. The marking system can also be similar to thatv described above; that is, the members 250. and 26a. may be so marked that when the same mark on each is turned to a pointer 35a. on frame member 6a, the axis E is adjusted in the desired plane so that the thread turns are advanced in a. helix having the desired pitch. Preferably, the marks on the edge of member 25a extend on the surface 38 of said member so that the correspondingmarks on the edge of member 26a can be adjusted as desired.

In this embodiment of the invention, intermediate member 25a is held on frame member 6a by bolts 45, each of which passes through a clamping member 46 hearing on the cornerof member 25w. Member 25a, is, of course, accurately located by shoulder 42. Similarly, member 26a is held against member 25a. by bolts 41 pass ing through clamps 48, being accurately located by means of shoulder '43. As shown, the edges of the front surface of each of said members 25a. and 26a. may be formed so that they are parallel to the rear surface of said member, thus making it simple to clamp said members against the member on which they are mounted.

It is apparent that in both illustrated embodiments of the invention, the adjustments can be made, if desired, without halting the operation of the reel. Thus the set screws clamping to gather the parts 25, 26 and 6 in the first em-- bodiment, orthe bolts clamping together parts 251;, 26a and Got in the second embodiment, may be loosened and the parts adjusted as desired, after which the set screws or bolts may be tightened, without in any way interfering with the in certain planes, the intermediate member may be moved in a predetermined plane.

Under such circumstances, of course, the adjustable axis will not It is apparent that the invention may be applied to reels of types other than that shown, being applicable in its broader aspects to the adjustment of parts other than, those of thread-advancing reels.
